Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. LFC liquid metal filling process, and metal flow front heat, mass and momentum transfer process. Dongying traditional sand casting stainless steel castings compared, resulting in the disappearance of molded type process more complex, not only directly related to the level of success and quality of castings cast molding and casting has a crucial impact on the intrinsic quality. As we all know, cast iron platform, pulley casting defects since the basic source of liquid metal to solidify liquid filling a short time, undergoing tremendous change in this short moment, the mold cavity, the presence of thermal decomposition look, appearance its advance in the liquid metal filling the gap occurs between the leading edge of steel castings, liquid metal filling forward blocked the flow of liquid metal filling state of great disorder occurs, causing the metal filling vacuum flow bi-laws have a serious effect, thermal Solutions of the gaseous product is discharged through the paint layer into the molding sand, the residual solid product of pyrolysis in the flow of the liquid metal filling the cavity is involved, the role of various impurities in the liquid metal by the negative pressure in the float movement becomes slow while some slack in the castings. Various physical and chemical reactions occurring phenomena are unable to see, as a cast in the production of "black box" .. Unlock the "black box.", Find the cause of defects produced castings, casting workers disappeared desire and longing coveted goal. Linyi Public Li Xin Machinery Co., Ltd. is the design, production, processing, marketing as one of modern science and technology enterprise, the use of advanced international casting today (EPC) of a negative real casting process to produce more material casting temperature resistance corrosion castings, abrasion resistant castings, steel castings and other antioxidant. Production process and quality in a leading position, with metal spectrometer, and other advanced detection equipment. Stomatal pores is one of the most common large pulley casting multiple defects, because according to the gas pores formed tee alloy steel castings, porosity divided into three types, namely due to the reasons for the formation of type casting invasive pores; because metal solution containing gas The precipitation of the components forming pores; the molten metal and the mold due to chemical interaction with each other is formed between the reactive pores. A stomatal invasive invasive pores is mainly due to surface accumulation of gas sand intrusion of molten metal is formed, the gas in the water from the mold material, a binder and various addenda and the like.
